Abstract: PURPOSE:To reduce the fluctuation of output power with respect to a change in the operating temperature by providing an operational amplifier amplifying a voltage change in a diode compensating a base current with respect to the operating temperature and applying the result to a base of a power amplifier transistor(TR). CONSTITUTION:An operational amplifier 10 of a base bias circuit amplifies a voltage change with respect to the operating temperature of a diode 6 and applies the result to a base circuit of a power amplifier TR 1. A forward voltage Vf of the diode 6 is amplified by the operational amplifier 10 and a voltage Vref to obtain an optional output voltage Vin is inputted to an inverting input of the operational amplifier 10 to apply an offset. When the operating temperature varies, since the forward voltage Vf of the diode 6 is changed, the output voltage V10 is changed and in terms of a change DELTAV10 in the voltage V10 at a temperature change, a change DELTAVf of the voltage Vf is amplified with an optional amplification value. Thus, a change DELTAhFE in the DC current amplification factor hFE of the TR 1 is compensated by the voltage V10.

Filed: 1981-12-28
Abstract: PURPOSE:To reinforce the magnetomotive force of a motor by providing an auxiliary winding at the prescribed electric angle delay from the primary winding at the primary side core and connecting it through a condenser to the same power source for the primary winding, thereby adjusting the phase angle of the main magnetic flux. CONSTITUTION:When a voltage V is applied to a power source terminal, the primary current I1 flows through a primary winding A, and the secondary electromotive force 2 is induced at the secondary coil A2. Simultaneously, an auxiliary electromotive force Ea is induced at the auxiliary winding B, but since the winding B is disposed at electric angle 120 deg. delay on the primary core, the auxiliary electromotive force Ea is delayed at 120 deg. in phase from the applied voltage V, and the auxiliary exciting current Ia' which leads at 90 deg. in phase from the condenser voltage flows through the auxiliary winding via a condenser V. The phase of the current Ia' is adjusted in the phase angle of the main magnetic flux by regulating the disposition and the number of turns of the winding B as described above, thereby increasing the magnetomotive force and improving the power factor.
